Description
Die Erfindung betrifft ein Flugzeugrad mit Bremstrommelausrüstung, bei welchem der seitliche Radteil zwischen Bremstrommel und Bereifung aus zwei mittels Querrippen verbundenen Kränzen besteht, wobei der obere Kranz als Felgenschulter und der untere Kranz als Bremstrommelauflage dient. Sie macht es sich zur Aufgabe, durch eine neue Ausführungsform in wärmetechnischer und festigkeitstechnischer Hinsicht wesentliche Verbesserungen gegenüber den seither bekannten Flugzeugrädern zu erzielen und dabei auch noch der Forderung nach möglichst geringem Gewicht Rechnung zu tragen.The invention relates to an aircraft wheel with brake drum equipment, in which the Lateral wheel part between the brake drum and tires made of two connected by means of transverse ribs There are wreaths, with the upper rim serving as a rim shoulder and the lower rim as a brake drum support. she makes it its business, through a new embodiment in thermal and technical In terms of strength, significant improvements compared to those known since then To achieve aircraft wheels and at the same time also the demand for as little as possible Weight to be taken into account.
Es sind Flugzeugräder bekannt, bei welchen die Bremstrommel und der Felgenkranz durch einige Querrippen, gleichzeitig aber auch durch eine an diese Rippen anschließende, längs verlaufende Vollwand verbunden sind.There are aircraft wheels known in which the brake drum and the rim by a few transverse ribs, but at the same time also by an adjoining these ribs, longitudinal solid wall are connected.
Bei einer anderen Radausführung stehen die Querrippen nicht in fester Verbindung mit der Bremstrommel, sondern schließen an einen Nabenkörper an und erstrecken sich auf die ganze Radbreite, Anderseits kennt man auch Räder, deren Querrippen nicht an den Felgenkranz heranreichen und bei denen eine durchgehende Wandung des Bremstrommelkörpers als Felgenabstützung dient. Ferner hat man schon eine Vielzahl von durchgehenden Rippen, die mit dem Felgenkranz zusammengegossen sind, angeordnet, dabei aber die Verbindung mit dem Bremstrommelkörper lediglich durch einzelne Laschen hergestellt. Ein Nachteil, der all diesen Ausführungsformen gemeinsam anhaftet, ist darin zu sehen, daß sie Gewichte ergeben, die neuzeitlichen Leichtbaubestrebungen nicht- entsprechen. Dann ist bei solchen Flugzeugrädern, die festigkeitstechnisch zweckentsprechend aufgebaut sind, nicht berücksichtigt worden, die bei sehr scharfen Bremsungen auftretenden Wärmemengen der Felge und damit der Bereifung nach Möglichkeit fernzuhalten. Andere · Flugzeugräder wieder, bei welchen die Querrippen Durchlüftungskanäle zum Zwecke der Abkühlung bilden, entsprechen festigkeitstechnisch nicht den auftretenden starken Stoßkräften, da der feste Verband zwischen den Rippen und der Felge sowie der Bremstrommel fehlt. Zur Vermeidung von Verformungen wurden seither immer nur die Querschnitte, insbesondere die der Felgenschultern, vergrößert, so daß die auftretenden Biegebeanspruchungen und Radstoßkräfte in der Felgenschulter allein aufgenommen werden konnten. Diese Maßnahmen führten aber zu unerträglichen Erhöhungen der Radgewichte.With another wheel design, the transverse ribs are not in a fixed connection with the Brake drum, but connect to a hub body and extend to the Whole wheel width, on the other hand, we also know wheels whose transverse ribs are not on the rim and in which a continuous wall of the brake drum body serves as a rim support. Further you already have a multitude of continuous ribs that are cast together with the rim are arranged, but the connection with the brake drum body is only made by individual tabs. A disadvantage common to all of these embodiments is to see that they result in weights that do not correspond to modern efforts in lightweight construction. Then with such aircraft wheels, the strength engineering is appropriately designed have not been taken into account, those that occur with very sharp braking Keep away heat from the rim and thus the tires if possible. Other · Aircraft wheels again, in which the transverse ribs ventilation channels for the purpose of Form cooling, do not correspond to the strong impact forces that occur in terms of strength, because the solid bond between the ribs and the rim and the brake drum is missing. In order to avoid deformations, only the cross-sections have been used since then especially that of the rim shoulders, so that the bending stresses that occur and wheel impact forces could be absorbed in the rim shoulder alone. However, these measures led to unbearable ones Increases in wheel weights.
Gegenüber den seitherigen mangelhaften Ausführungsformen kennzeichnet sich das erfindungsgemäße Flugzeugrad dadurch, daßThe embodiment according to the invention is distinguished from the previous defective embodiments Aircraft wheel in that

die in bekannter dichter Folge angeordneten Querrippen als einzige Abstützung zwischen dem waagerechten Teil des Brems tr ommelträsfers und der Felge als einheitliches GuKri stück mit beiden einen steifen Rahmenträg^j bilden und sich hauptsächlich nur etwa ί>ί^ zur seitlichen Felgenbettwand erstrecken. '*i The transverse ribs, which are arranged in the known close sequence, are the only support between the horizontal part of the brake drum drum and the rim as a uniform piece with both of them to form a stiff frame support and mainly extend only about ί> ί ^ to the side wall of the rim well.
